Effects of geraniol on memory functions in the brain of studied groups: the Morris water maze (MWM) was used to evaluate (a) escape latency for young rats, (b) escape latency for aged rats, (c) escape distances for young rats, (d) escape distances for aged rats, (e) the percentage of time spent for young rats, (f) the percentage of time spent for aged rats, (g) distance swum in the target quadrant for young rats, and (h) distance swum in the target quadrant for aged rats. Three independent experiments were carried out. Values are expressed as the mean ± SEM (n = 8). Means with different letters in each bar (A–D) are significantly different (p < 0.01), where the largest data value takes the letter (A) and the smallest data value takes the letter (D).
